"By passing this resolution tonight, the Portland Police Bureau is not re-joining the Joint Terrorism Task Force," Leonard said at the time.

"I think this is light-years ahead of that," Saltzman said of the new agreement, comparing it to Portland's decision in 2005 to pull out of the task force.

So, a month after that vote, The Oregonian is taking a look at how the language from the agreement changed over the many months of complicated negotiations that led to the April 28 decision.

Portland Mayor Sam Adams originally called for a vote on Feb. 24 but canceled that meeting one day before hand to "finalize input from various stakeholders," according to a press release.

At the same time, according to documents obtained under the state's public records law, city attorneys had drafted a memorandum of understanding for participation in the task force. That document mirrored the FBI's standard memorandum of understanding but featured many changes, such as:

Additional language about the mission: "To honor this mission, JTTF must conducts its operations in a manner that protects and preserves the constitutional rights and civil liberties of all persons in the United States."

Portland also added an oversight section, which included: "PPB participants on the JTTF will remain subject to the personnel rules, regulations, laws, and policies applicable to employees of the PPB. PPB participants in the JTTF shall at all times comply with the limitations imposed by ORS 181.575 and 181.850. PPB participants shall promptly report any violation of ORS 181.575 or 181.850 to the Chief of Police of the PPB."

With regard to a staffing commitment, the JTTF standard agreement calls for at least two years. But the Portland proposal said the "Chief of Police will determine the staffing commitment to be made by the PPB, in consultation and with approval of the Commissioner-in-charge of PPB."

U.S. Attorney for Oregon Dwight Holton has said that the FBI is in the process of re-writing its standard agreement, which is why the Portland City Council eventually approved a resolution that did not include the memorandum. But Leonard has also said that he would not have supported a relationship involving a memorandum of understanding.

On March 8, Adams canceled a meeting scheduled for March 10 after receiving "significant new input from federal agencies," according to a news release.

On March 10, the city attorneys office drafted a resolution that would have set protocols for Portland's participation in the task force. Adams also canceled a March 17 meeting. The resolution the attorneys office drafted would have established seven protocol sections, each with various measures.

But then Leonard negotiated the final agreement over the weekend. While adding language such as "criminal nexus," the final version approved by the City Council eliminated the standard operating protocols, included as an attachment, from the resolution.
